I've tried to download scripts to add to my messanger, but I can't find a program on my conputer to run it on. Everytime I click find one online it gives me a error message. Please help!

What error message are you getting?

Well now it's giving me the open option after I click download, but when I click open it tries to open it via Internet Explorer which brings up the Explorer windows for a brief second before taking me right back to the open/save window.

From inside Messenger Plus! Live's preferences window, navigate to scripts (on the left-hand side) and then there should be an import option. Save the script to the desktop and then select it. It should then import.
